Issues importing Pytides

[deborarodriguesp]

Hello!

So I was able to install pytides, and my code starts as:

from datetime import datetime
from pytides.tide import Tide

but I am having an error:

Traceback (most recent call last):
  File "D:\DOUTORAMENTO\Tide\Tide_Extractor\predict_tidal_signal.py", line 2, in <module>
    from pytides.tide import Tide
  File "C:\Users\Debora\anaconda3\envs\tide\Lib\site-packages\pytides\__init__.py", line 3, in <module>
    import tide
ModuleNotFoundError: No module named 'tide'

I don't know why, I opened the init file, and it seems fine. I also have tide.py in my folder, so I don't understand the issue...

Can somebody help me?

The init file from pytides is:

 # -*- coding: utf-8 -*-

import tide
import astro
import constituent
import nodal_corrections

Okay, so I found the alterations made by others in the init file, such as:

from . import tide
from . import astro
from . import constituent
from . import nodal_corrections

or

__all__ = ['tide', 'astro', 'constituent', 'nodal_corrections']

but I still have issues:

Traceback (most recent call last):
  File "D:\DOUTORAMENTO\Tide\Tide_Extractor\predict_tidal_signal.py", line 2, in <module>
    import pytides
  File "C:\Users\Debora\anaconda3\envs\tide\Lib\site-packages\pytides\__init__.py", line 3, in <module>
    from . import tide
  File "C:\Users\Debora\anaconda3\envs\tide\Lib\site-packages\pytides\tide.py", line 2, in <module>
    from collections import OrderedDict, Iterable
ImportError: cannot import name 'Iterable' from 'collections' (C:\Users\Debora\anaconda3\envs\tide\Lib\collections\__init__.py)

Hello,

What python version do you use?
if you use python >3.10, you can try to modify the "tide.py" file.
change:
from collections import OrderedDict, Iterable
to:
from collections import OrderedDict
from collections.abc import Iterable

Or downgrade the python to 3.9.

Best wishes.

Hello!

Thanks for the help, it did work!
But I still have other issues...

So, I have harmonic components information from FES2014, and I want to use it as input for my model, but said model only allows water level, thus I need to predict the water level. I am following this guide:

For now, this is my code:

# Specify the folder where your files are located
folder = 'D:/DOUTORAMENTO/Tide/Tide_Extractor/output/'

# Get a list of all files in the folder
fileList = [f for f in os.listdir(folder) if f.startswith('tidal_data_point_') and f.endswith('.txt')]

times_to_predict = [datetime(2008, 1, 1, 0, 0, 0), datetime(2022, 1, 1, 1, 0, 0)]

# Loop through each file
for fileName in fileList:
    # Build the full path to the current file
    filePath = os.path.join(folder, fileName)

    # Extract latitude and longitude from the file name
    latLong = [float(val) for val in fileName.replace('tidal_data_point_', '').replace('.txt', '').split('_')]
    latitude, longitude = latLong[0], latLong[1]

    # Read the data from the file
    data = pd.read_csv(filePath)
    
    # Extract necessary columns (Harmonics, Amplitude, Phase)
    constituents = data['Harmonics']
    amplitude = data['Amplitude']
    phase = data['Phase']

    start_time = datetime(2008, 1, 1, 0, 0, 0)
    
    assert(len(constituents) == len(phase) == len(amplitude))
    model_dtype = np.dtype([('constituent', object), ('amplitude', float), ('phase', float)])
    model = np.zeros(len(constituents),dtype=model_dtype)
    
    model['constituent'] = constituents
    model['amplitude'] = amplitude
    model['phase'] = phase
     
    model = np.array(model, dtype=model_dtype) #class 'numpy.ndarray'

    tides = Tide(model = model, radians = False)
    print (tides)
    sys.exit()            

    predictions = Tide.at(times_to_predict)

    print(predictions)

But I have an error related to this line:

tides = Tide(model = model, radians = False)

Traceback (most recent call last):
  File "D:\DOUTORAMENTO\Tide\Tide_Extractor\predict_tidal_signal.py", line 45, in <module>
    tides = Tide(model = model, radians = False)
            ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
TypeError: 'module' object is not callable

My model is like this when I ask to print:

type: class 'numpy.ndarray'

So I am not sure if this is the right...
